Yeah, I too have it pretty bad. My gf takes the piss out of me all the time for it - no mercy. I'm currently building her up a fixie and I'm sure she'll get hooked too (I hope).
As for girls on fixies - I have seen none. That's right, ZERO, in Glasgow. They remain some sort of urban myth perpetuated by the internet and other such heathen tools of visual communication.
My staring is more or less limited to the courier hot-spot along from where I work. Pretty much the only place to see fixies in Glasgow......
